Langlands correspondence and Bezrukavnikov's equivalence
Course given at the University of Sydney, first semester 2019.

Abstract: A course in two parts:
1) an attempt to explain what the Langlands program is about from an arithmetical point of view;
2) affine Hecke algebras, Deligne-Langlands conjecture and Bezrukavnikov's equivalence.
